ANGLE-COCK.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed January 29, 1907. Serial No; 354,761-

To all whom it may OOH/0.677%.

Be it known thatwe, WILLIAM H. WooDY,

of Ohambersburg, in the county of Franklin and State of Pennsylvania, and FRANKLIN CA BY and PALMER TENNANT, of Hagerstown, in the county of Washington and State of Maryland, have invented certain new and useful Improvements in Angle -'C0cks, of

whichthe following is a specification,

thereforz' Its objects are principally to provide for exhausting the air-pressure remaming in the train pipe-sections after the closing I of the train-pipe valve or angle-cockas' in applying the brake's'in an emergency or-for use as a service brake; and for facility in uncoupling the hose or flexible pipe sections; andto carry out these purposes in a simple, economic and effective manner.

Said invention consists of certainfeaturesor instrumentalities substantially as herein- 1 after fully fdi'sclosed and specifically pointed.

out by the claims.

.In the accompanying drawing illustrating the preferred embodiment of my invention- Figure -1 is a side elevation thereof. Fig. 2

isa vertical longitudinal section taken through the angle-cock, withthe latter in closed position.' Fig; 3 is a vertical transverse section produced through the relief or exhaust valve. Fig. 4 is a like section with the parts as ma nipulated in opening said relief or exhaust valve. Fig. 5 is a horizontal section proliuced" through the relief or exhaust ,valve and its port or passage opening 'nto the port or passage. of the angle-cock lug-and the supplemental port of the latter,the same be ing shown in closed position.

In carrying out my invention, I providethe angle-cock 1 in general outline of the usual construction, except as to the nozzle. or end of the casing or casting thereof to =for effecting-the coupling therewith. of the usual flexible pipe or hose section between the cars as will be readily understood.

'An'anged laterally of the angle-cock 1 and outstanding therefrom a short distance is what may be termed generally the relief or exhaust valve 3, the same comprising a tubular inclosure or shell 4 of preferably T.-formation with its stem-member arranged horiz'on tally and screwed a suitable distance into the casting or casing of said angle-cock. In

alinement with the interior of said stemmember of saidinclosure or shell lis' a port or passage 5 formed in, the casting of the angle-cock and opening thereinto and into the chamber of-said casting 'ust opposite the plug 6- of the angle-cock.

aid plug is also provided with a port 7 opening into the usual port or passage 8 thereof, and which is ef- 'ective for cooperation with the port or passage 5 and the relief or exhaust valve as presently more fullymade apparent. -Within "said casing or shell l is arranged a valve 9 normally held closed or'seating upwardunder the action or stressjof a preferably helical spring 10, this, however, also being supplemented by the air-pressure within, f0r keeping the opposite ports 11, 12 in the shell or casing 4 initially closed.

When it -may be required to apply the brakes, the anglecock lever 13 is swung around, accordinglyturning its plug until the usual lug orlugs thereof engage the stops prov-ided upon the angle-cock casting as usual,

thus cuttin off the sourceof air-pressuresupply to t e flexible or hose sections and consequently to all the successive pipe and hose sections of the train-pipe. Simultaneously with such movement of parts, the

lever 13 havin now been brought around in alinement with the exhaust valve 3, said lever is forced downward, it being capable also of vertical movement and of the type of lever already in use in connection with angle cocks on railroad air.- brakes. The down ward movement of said lever will bring it into enga ement with the stern of the valve 3 according ly. unseating the latter which will open the exhaust ports 11, 1 2 in the exhaustvalve casing, thus allowing the confined airpressure within the following hose or flexible and other pipe-sections of the train-pipe to be exhausted which, of course, will result in applying the brakes and bringing the train to a standstill. 'It will be understood that this manipulation of parts is pi formed by thetrain-conductor or brakeman, as'in an emergency, as an Instance of which, It may be noted, when the signals cannot be seen by the engineer, as well as under other conditions which it may not be necessary toluention herein: Also, it is observed that this device is equally available as a brake-valve in service, as well as an emergencystop-brake. Its use also provides for the exhausting of airpressure from the flexible or hose sections, to remove premature wear and mutilation of gaskets at hose-section joints, as in parting or uncoupling the same, While this may be done with greater facility orfreedom from embarrassment than when air-pressure remains in said hose-sections, as is apparent. It also prevents the liability, with the air-pressure exhausted, as by its use, of the blowing out of gasketsor packings in parting or uncouppling the hose-sections; also it has no connection with the train pipe-line when the angle-cockis in working position. It cannot be applied in the event of the accidental breaking in any 'wayof the valve or adjunctive parts when the angle-cock is in operative position, and it is not liable to get out of repair or become inoperative by freezing or otherwise becoming chokedor stopped up. In the use of the angle-cock with its casting provided with a laterally deflected nozzle, the hose-sections are adapted to be retained in a straight line,which prevents undue wear andbreaking of the latter in effecting the coupling and uncoupling thereof, as well as renders the handling of the same with more ease or facility.

I claim- 1. A device of the character described, having an air-pressure brake cock,"and an exhaust valve effective in connection with said cock and with the hose or pipe coupling for applying the brakes and for exhausting the air-pressure from said hose or pipe coupling.

2. A device of the character described, having an air-brake pressure cock and a valve with its port-passage effective for cooperation with the usual passage or port of said cock and an additional port communicating with said angle-cock passage and with the hose or pipecoupling, for exhausting the air brake pressure from the train-pipe in cluding the hose or pipe coupling.

3. A device of the character described, having an air-brake pressure cock, provided with an additional port communicating with its usual air-passage or port, said cock also having its casting or casing provided with a lateral port or passage, and an exhaust valve having its casing provided with opposite ports and an upward seating valve proper,

for controlling said opposite ports, said valve-' said angle-cock, and provided 'Withan upward seating valve controlling opposite ports in said valve-casing, and means, in common with that for operating said angle-cock, for actuating said exhaust or relief valve.

5. A device of the character described,-

having an air-pressure brake-cock, and a relief or exhaust valve eflective in connection,

with said air-pressure brake-cock for exhausting the air-pressure from the hose or pipe coupling, and means in common with that for turning or closing said air-pressure brake-cock, for de ressing or opening said reliefor exhaust va ve.

6. .A, device of the character described, having an air-pressure brake-cock provided with an additional port communicating with its usual straight away passage or port through a lateral wall of said passage, and a relief or exhaust valve effective for co-operative action with said air-pressure brake-cock, said additional port adapted to be brought into communication with the hose or pipe coupling as said air-pressure brake cock is turned'to close off communication between its usual straight-away passage or port and the train-air pipe line.

In testimony whereof we afiix our signatures, in presence of two witnesses.
